Thanks in Advance
In theory you can Interpolate a Helical Thread on a 5 Axis Lathe. But you need a true Y and C Axis to do this. Also you will need to find the G-Code Designation that will Synchronize the C Axis with the Y Axis. What this will do is replace the Y Axis with the C Axis. Maybe a G100, G101, G120, G121, G200, G201, G300, or G301. You may also have to Designate a Work Plane.
This is still a 3 Axis movement but in the C, Z, and X Axies. It is the Same as an XYZ Movement but you are substituting the Y for the C and the X is now your Depth in the part.
What Machine, and Control Are you trying this on??
I have done this once before on a Nakamura-Tome. I will try to find the Program so you can see it.
G76 to my knowledge is only used for the XZ Plane, G18.
